Constitutive expression of antimicrobial peptide PR-39 in transgenic mice significantly enhances resistance to bacterial infection and promotes growth.
Article in Transgenic research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Use of huge amounts of antibiotics in farm animal production has promoted the prevalence of antibiotic-resistant bacteria, which poses a serious threat to public health. Therefore, alternative approaches are needed to reduce or replace antibiotic usage in the food animal industry. PR-39 is a pig-derived proline-rich antimicrobial peptide that has a broad spectrum of antibacterial activity and a low propensity for development of resistance by microorganisms. To test whether ubiquitous expression of PR-39 in transgenic (TG) mice can increase resistance against bacterial infection, we generated TG mice that ubiquitously express a pig-derived antimicrobial peptide PR-39 and analyzed their growth and resistance to infection of the highly pathogenic Actinobacillus pleuropneumoniae (APP) isolated from swine. The growth performance was significantly increased in TG mice compared with their wild-type (WT) littermates. After the APP challenge, TG mice exhibited a significantly higher survival rate and significantly lower tissue bacterial load than WT littermates. Furthermore, the tissue lesion severity that resulted from APP infection was milder in TG mice than that in their WT littermates. This study provides a good foundation for the development of PR-39-expressing TG animals, which could reduce the use of antibiotics in the farm animal industry.
